1678 | The kernel memory allocator divides physically contiguous memory | ||
1679 | blocks into "zones", where each zone is a power of two number of | ||
1680 | pages. This option selects the largest power of two that the kernel | ||
1681 | keeps in the memory allocator. If you need to allocate very large | ||
1682 | blocks of physically contiguous memory, then you may need to | ||
1683 | increase this value. | ||
1684 | |||
1685 | This config option is actually maximum order plus one. For example, | ||
1686 | a value of 11 means that the largest free memory block is 2^10 pages. | ||
1687 | |||
1688 | The page size is not necessarily 4KB. Keep this in mind | ||
1689 | when choosing a value for this option. | ||
